Passivity-based adaptive trajectory control of an underactuated 3-DOF overhead crane

Control Engineering Practice, 2021
This paper presents a robust passivity-based adaptive control method for payload trajectory tracking of a three degree-of-freedom overhead crane with a varying-length rigid hoist cable.

Adaptive Anti-Swing Control for 7-DOF Overhead Crane With Double Spherical Pendulum and Varying Cable Length

IEEE Transactions on Automation Science and Engineering
Three dimensional (3D) overhead crane is a typical multi-input multi-output (MIMO) and underactuated mechatronic system. Complex double spherical pendulum dynamics and varying cable length increase the difficulty of the swing suppression control for ...

Vibration and Position Control of Overhead Crane With Three-Dimensional Variable Length Cable Subject to Input Amplitude and Rate Constraints

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2021
In this paper, the modeling and control problem of an overhead crane equipped with a three-dimensional (3-D) variable length flexible cable is discussed. In order to achieve high control performance, a partial differential equation (PDE) model is deduced

Optimal control of overhead cranes

Control Engineering Practice, 1995
Abstract A nonlinear dynamic model of an overhead crane which represents simultaneous travel, traverse, and hoisting/lowering motions is considered. Nonlinear feedback forms of control are studied, and numerical results are obtained in such a way that specified boundary conditions and the functional constraints for the states and controls are ...

Integrated time-optimal rigid-body and zero-vibration shapers on a two degrees of freedom overhead crane system

Journal of Vibration and Control
This study presents a novel control strategy for an overhead crane system controlled by a predefined acceleration function covering the whole range of the rest-to-rest maneuvers.

Energy Efficiency of Overhead Cranes

IFAC Proceedings Volumes, 2014
Abstract Energy efficiency is firstly considered into the control of overhead cranes. Based on the model of crane system, energy consumption as well as operational safety is formulated in an optimal control problem. The optimal control is used to search optimal trajectories of velocity and acceleration for minimizing energy consumption.

Input shaping for non-zero initial conditions and arbitrary input signals with an application to overhead crane control

International Workshop on Advanced Motion Control, 2022
Input shaping is a well-established approach for suppressing oscillations and vibrations in systems with flexible modes. When applying input shaping, it is common to assume the system to be at rest initially, i.e.

Robust Control Schemes for an Overhead Crane

Journal of Vibration and Control, 2001
This paper addresses the control problem of an overhead crane. A variable structure control scheme, a variable structure controller in conjunction with a state feedback control scheme, and a μ-synthesis control scheme are proposed to control the overhead crane.

Comprehensive Analysis of Input Shaping Techniques for a Chain Suspended from an Overhead Crane

Journal of Vibration and Acoustics
This work investigates the use of input shaping techniques for controlling oscillations in a chain suspended from an overhead crane, aiming to enhance crane operations without sacrificing speed or safety. The study focuses on two specific input shaping

Vibration Control of an Overhead Crane with Hoisting Motion using Input Shaping Technique

American Control Conference, 2022
In this paper, an input shaping-based control law is designed for an overhead crane system with time-varying cable length. The proposed method employs a zero vibration (ZV) input shaper. It is well-known that the ZV input shaper is not robust to modeling
